Description

Overhead line laser system of removing obstacles

Technical Field

The utility model relates to a power equipment overhauls and maintains the field, especially an overhead line laser system of removing obstacles.

Background

The overhead line is an important component of a power grid, and the periodic inspection of the overhead line is a basic work for effectively ensuring the safe operation of a power transmission line and equipment thereof. In recent years, with economic development, regional construction and other reasons, the change in the corridor of the transmission line is frequent, and the line trip caused by the channel problem becomes a main reason of the transmission line fault. Especially, foreign bodies such as plastic cloth, plastic bags, kites, kite lines, advertisement banners, fishing lines, Kongming lamps, sunshade nets, balloons, dustproof cloth, sunshade cloth and the like are blown down onto overhead lines to form foreign bodies, namely the double rectangular bags, which become main causes. Even plants planted below the power transmission line threaten the power transmission line due to the upward growth of treetops, and if the treetops grow to directly contact the power transmission line, faults such as interphase short circuit or single-phase grounding of metal wires can be caused. This will have great potential safety hazard to people and livestock, has reduced the reliability of electric wire netting power supply, leads to electric power system to be unable to operate safely, and then causes huge economic loss to electric power system. Therefore, timely cleaning of foreign matters on the power transmission line is of great significance to the power system.

The method is a safe, convenient and quick clearing mode, and solves the problems of high operation cost, low efficiency, high operation risk and the like in the overhead line clearing in the prior art. However, due to the fact that infrared laser is invisible to human eyes and high in laser brightness, once untrained non-professional operators operate by mistake or enter a laser emission area carelessly, the operators and surrounding personnel are easily burnt, and potential safety hazards exist.

Patent CN205724660U discloses a remote laser obstacle clearing system, which adopts a structure as shown in fig. 1.
